noviembre de 2003 Conclusions •Need to carry out key pressures analysis - representative impact to analyse POM •Complexity in good status threshold definition and need of intercalibration •Usefulness of modelation in GIS for POM effectiveness analysis: Serpis pilot case •Quality National Plan: Basic Measures •Need for analysis methodologies: •Complementary measures - less rigourous objectives. •Exception Possibilities: costs out of proportion noviembre de 2003 noviembre de 2003
